Apache Spark reassigned SPARK-24992:
------------------------------------
Assignee: Apache Spark
> spark should randomize yarn local dir selection
> -----------------------------------------------
>
> Key: SPARK-24992
> URL: https://issues.apache.org/jira/browse/SPARK-24992
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.1
> Reporter: Hieu Tri Huynh
> Assignee: Apache Spark
> Priority: Minor
>
> Utils.getLocalDir is used to get path of a temporary directory. However, it
> always returns the the same directory, which is the first element in the
> array _localRootDirs_. When running on YARN, this might causes the case that
> we always write to one disk, which makes it busy while other disks are free.
> We should randomize the selection to spread out the loads.
